Note
Do not enter the show memory summary command with the terminal length 0 command enabled. If
you do, many screens of output might interrupt your session.

CPU Utilization
Enter the show process cpu command and then the show process cpu history command to investigate
high CPU utilization. High utilization causes network performance problems. For example, knowing
when the router is running at over 50 percent utilization is critical. The router might start dropping
packets if an unexpected traffic burst comes through or if Open Shortest Path First (OSPF) is
recalculated. Fast switching can also be used to reduce CPU utilization.

The show processes cpu history command displays in ASCII graphical form the total CPU usage on the
router over a period of time: one minute, one hour, and 72 hours, displayed in increments of one second,
one minute, and one hour, respectively. Maximum usage is measured and recorded every second; average
usage is calculated on periods over one second.
